Fig. 7From: Bacterial community structure and co-occurrence networks in the rhizosphere and root endosphere of the grafted applePrincipal coordinate analysis (PCoA) (a) and Clustering analysis (b) of the bacterial communities associated with the rhizosphere and root endosphere of grafted apple. MH, M9, MB and MR represent the rhizosphere from Malus hupehensis Rehd., M9T337, Malus baccata Borkh. and Malus robusta Rehd., respectively. MHR, M9R, MBR and MRR represent the root endosphere from Malus hupehensis Rehd., M9T337, Malus baccata Borkh. and Malus robusta Rehd., respectively. Bk represents bulk soilBack to article page
